Troy Davis was executed Wednesday night by way of lethal injection for the murder of a Georgia police officer. An eleventh-hour plea to stop the execution, filed by Davis' defense team, was denied by the U.S. Supreme Court – leaving supporters worldwide both saddened and outraged.

Davis advocates have voiced their feelings across various social media platforms, including Twitter, where someone created an account dedicated to Troy Davis.

Also, the hashtag "#RIPTroyDavis" has become the second most-talked about topic on Twitter, according to the site's Trend list.

@RIPTROYADAVIS tweeted, "Casey Anthony gets a book deal, while #TroyDavis got a last meal. Charles Manson is still alive, and an innocent man just died. #RIPTROYDAVIS."

The Troy Davis account, which states, "He was shown no justice, no mercy, but he still forgave. He is in our hearts and minds. Follow to show support for him and the message he has brought us,” has attracted over 50,000 followers."
